In the last two decades, there is a global trend, the so-called nutrition transition, which is characterized by a decrease in the number of people with malnutrition and an increase in obesity levels. In Brazil, data from the Pesquisa de Orçamento Familiar (POF), conducted between the years 2008 and 2009 show that 49.0% of the total population of adults are overweight and 14.8% are considered obese. Thus, the aim of this study is to characterize the profile of patients seeking nutritional home. The study was characterized as exploratory, cross country, descriptive quantitative approach, in which we analyzed 38 case histories of patients who received nutritional care home (personal diet). The majority (84%) of the patients were females and the average age was 33.53 years. With respect to nutritional status (47%) are in the overweight range or at some level of classification of obesity and (74%) have tried some kind of diet for weight reduction previously. When asked about the emotional state (74%) were considered anxious. Through this study, we see the need to develop strategies in partnership with the patient, so that it is able to understand the importance of adding new habits, in order to find the solution to this problem.

Caffeine stimulates fatty acid mobilization by increased catecholamine release. The fatty acid oxidation spares muscle carbohydrate stores resulting delaying fatigue. Objective: The aim of this study was to investigate whether the influence of caffeine on lipolysis induces a reduction in blood glucose levels during an indoor cycling class. Materials and methods: Primary, clinical, prospective, analytical, controlled, comparative, observational study, performed at a single center. Participated in the study 19 men with mean age of 35 ± 8.1 years, physically active for at least 6 months 3 times a week. The subjects were randomly assigned to placebo (n = 7) and caffeine group (n = 12). The caffeine group received 5 mg/kg of caffeine 30 min before carrying out a ciclism indoor class. All participants ingested the same pre-test meal and fasted for 8 hours before the test. Two blood samples were collected, one at arrival, prior to the ingestion of caffeine and the second immediately after the exercise. Total cholesterol, triglycerides, HDL, LDL, VLDL, glucose, urea, creatinine, uric acid and lactate were measured. The study was double blind and statistical analysis was used from the Student's t test, considering significant p values <0.05. Results: There was statistical difference only in HDL (p<0.05) among both CG and PG and between individuals of each group. We conclude that caffeine consumption under the conditions of this study did not alter the lipid profile in order to induce a reduction in blood glucose levels and delay fatigue during an indoor cycling class.
